Concurrency control in multi-user microcomputer database management systems

Abstract The past few years have seen a dramatic increase in the business use of centralized multi-user microcomputer DBMSS without a concomitant attention to the concurrency control mechanisms employed by those DBMSS to ensure the integrity of the data they manage. This paper examines the state-of-the art, examines the types of work done previously on the performance of DBMS concurrency control, and proposes independent measures to be used in an empirical study to evaluate the efficiency and effectiveness of multi-user microcomputer DBMS concurrency control.
